add /IGNORE:4216 to HAL link step, add writing and directory listing to the FAT32 driver, add the concept of current working directory to the VFS, add writing to the VFS, more operations in the shell, rename KeCurrentThread to KeGetCurrentThread and add KeGetCurrentProcess, add STATUS_NO_MORE_FILES, change KeFault* to KePanic, add syscalls for writing to files, add a proper syscall to writing to the console, move Screen.Clear to after memory status debug print, add ObjectTypeDir to OBJECT_TYPE, extend kernel32 by file operations and upgrade user32 (and add gdi32) to match windows a bit more closely, change CreateProcessA to accept the first argument as NULL.
